steradians's Usage Examples:

the fact that such detectors are designed to cover nearly all of the 4π steradians of solid angle around the interaction point; in terms of the standard.

A full sky survey would collect objects from the entire sphere, 4π steradians, of sky but this is usually impractical, both from time constraints and geographical limitations (ground-based telescopes can only see a limited amount of sky due to the Earth being in the way).

The BRDF has units sr−1, with steradians (sr) being a unit of solid angle.

the first detector to uniformly cover as much of the 4π steradians (units of solid angle) around the interaction point as possible with different.

degree being equal to π/180 radians, a square degree is equal to (π/180)2 steradians (sr), or about 1/3283 sr or 3.

40 mW, since there are 4π steradians in a sphere.

Whereas an angle in radians, projected onto a circle, gives a length on the circumference, a solid angle in steradians, projected onto a sphere, gives an area.

factor π {\displaystyle \pi } (which really should have the units of steradians) is a result of the fact that intensity is defined to exclude the effect.

1 spat is equal to 4π steradians or approximately 41253 square degrees of solid angle (sequence A125560 in the OEIS).

A full sphere has a solid angle of 4π steradians, so a light source that uniformly radiates one candela.

constellations is the total solid angle of the sky, which is exactly 4π steradians, or 4π × (180/π)2 129,600/π square degrees, or approximately 41,252.

an object that blocks all rays from the apex would cover a number of steradians equal to the total surface area of the unit sphere, 4 π {\displaystyle.

1 spat is equal to 4π steradians or approximately 41253 square degrees of solid angle (sequence A125560.
